Hello guys, I have a t-rb22 logitech trackball and at the moment it's not working properly. I have thinkered with it a bit, I think I know what the problem is and I need to replace a small switch inside (pictures attached).
This switch - well I call it switch - has a little pin at the back not visible in the picture that gets pushed in everytime a button is clicked on the trackball (it's the main left mouse click). I am not really techincal when it comes to these things and I have absolutely no idea where to buy it. It's a 426c IC (as you can see) and there is also a white cover that says 002069-0000 cav4. WOuld anybody know where and if I could buy this part anywhere or where I could get more info? Oh logitech don't sell this trackball anymore so no point asking them.
